ATT already has the atrix from moto which is similar. we do not charge extra for tethering with the atrix. i don't think att will require tethering because if you use extra data you will have to pay for it at $10/GB just like any other phone

Yes you can plug your atrix up without having the tethering package. However if you want to click on Mozilla and use it like you would an actual laptop you would need the $45 4GB Tethering package. Otherwise you are using the browser on the phone and not Mozilla. Being an ATT rep you should know that. Otherwise you are misleading your customers. I can look up the bill code for and tell you exactly which bill code that is if you would like. I have sold many of these.
